On April 3, 1748, in Middlesex County (now considered outer London) Mary Ryder was convicted of stealing several items of clothing including four petticoats, an apron, and a shirt, from William Rump and Elizabeth Cole. She was sentenced to 7 years transportation and shipped on the Mary commanded by Capt. Lewis Brown, arriving in Annapolis in October 1748.
Dr. Charles Carroll likely purchased her indenture and put her to work as a seamstress, washer woman, or house servant in his Annapolis home. Only six months later, in April 1749, Dr. Carroll took out an advertisement saying she had run away. He described her appearance, the clothes she was wearing, and warned she “pretends to be a seamstress and is much given to Drunkeness and taking snuff.”
